Arbutifolium

Arbutifolium is a botanical name that has appeared in the plant taxonomy literature but is not currently recognized as a valid genus by major taxonomic databases. In contemporary classifications, it is generally not treated as a distinct, accepted genus, and when encountered, the name is usually considered historical, provisional, or as a synonym rather than a standing taxon.

Etymology and usage: The term combines arbutus, the Latin name for the madrone or strawberry tree, with folium, leaf, conveying a sense of arbutus-like foliage. Throughout botanical history, arbutifolium has been used in different ways. Some authors applied it as a genus name for evergreen shrubs with leaves reminiscent of Arbutus; others used it as a species or varietal epithet within other genera. Because there has been no single, stable circumscription, taxonomic treatments have varied: some treated arbutifolium taxa as synonyms of Arbutus or related groups, while others treated it as a separate but non-standard genus. In modern practice, plant names tend to be resolved into widely accepted genera, so arbutifolium is most often encountered in historical literature or discussions of nomenclatural history rather than as an active, current taxon.
